Mercedes-EQ’s Nyck de Vries took victory in one of the wildest finishes in the history of Formula E, leading home Nico Mueller (Dragon/Penske Autosport) and his Mercedes teammate Stoffel Vandoorne.

Energy management is central to the racing in Formula E, and with the rain-hit race at the Circuit Ricardo Tormo requiring five appearances for the MINI Electric Pacesetter safety car, teams’ carefully calculated energy management strategies were thrown out of kilter with the round running a lap longer than had been expected.

De Vries had been happy to sit behind long-time leader Antonio Felix da Costa (DS Techeetah) and conserve energy for a late attack. As it happened, that attack turned into a two-lap sprint following the final spell under the safety car. However, only those who’d gone long as contingency, and conserved their usable energy, had enough power left in their cells to complete the extended race distance.

Dutchman de Vries drove by da Costa as the Portuguese driver was among many forced to slow with the race running beyond its anticipated finish. Mueller and Vandoorne — who had been stripped of his pole position on a technicality and sent to the back of the grid — making the final step on the podium.

Nick Cassidy (Envision Virgin Racing), Rene Rast (Audi Sport ABT Schaeffler), Robin Frijns (Envision Virgin Racing), da Costa, Alexander Lynn (Mahindra Racing), Sam Bird (Jaguar Racing) and Lucas di Grassi (Audi Sport ABT Schaeffler) rounded out the top 10. Jake Dennis (BMW i Andretti Motorsport) and Jean-Eric Vergne (DS Techeetah) were the only other drivers who were classified.

With the rain falling and the safety car leading the pack away, da Costa pulled a gap on Maximilian Guenther (BMW i Andretti Motorsport) and Lynn with the pack cleanly away as the race went green, for a lap or two at least.

Andre Lotterer and Sebastien Buemi had a coming-together at the hairpin — the Porsche man collecting the Nissan e.dams driver -= leaving the Swiss beached in the gravel.

A lengthy spell back under the safety car followed for the recovery of Buemi’s Nissan, with leader da Costa leading the pack away — and able to get the jump on the rest once again to the tune of two seconds once the green flags waved.

Guenther’s BMW was proving to be the cork in the bottle on Lap 5, with Lynn, de Vries, Norman Nato (ROKiT Venturi Racing), Oliver Rowland (Nissan e.dams) and Alexander Sims (Mahindra Racing) all within two seconds of one another. Lynn’s Mahindra suffered some front-end damage in the battle for Guenther’s second spot, and de Vries was able to pass the Briton and immediately make it by Guenther, too.

On Lap 6, Rowland passed Nato for fifth and Sims followed before Lynn sliced by Guenther’s BMW to recover a prospective podium position.

With 25 minutes plus one lap to run, out-front it all looked calm and collected for da Costa with the Portuguese firmly in his groove. De Vries held second, three seconds back but two seconds clear of Lynn in third. Rowland, Guenther, Sims, Nato, Pascal Wehrlein (TAG Heuer Porsche), Cassidy and Edo Mortara (ROKiT Venturi Racing) rounded out the top 10.

Guenther’s race came to a sticky end on Lap 10 as the Bavarian beached his iFE.21 having slipped down the order as far as sixth after complaining of a lack of grip in tricky, slippery conditions. The BMW snapped under braking as he clipped a white line and despite an armful of opposite lock, Guenther couldn’t prevent the inevitable and ended up trapped in the gravel.

The safety car made another appearance while the BMW was cleared and da Costa jumped early when the race went green once again — Mercedes’ de Vries all over his diffuser.

Mercedes was content to have the Dutchman remain in the leader’s slipstream, though, with energy management looking likely to come to a head towards the final minutes of the race. This would force da Costa into punching a hole in the air and use more energy in doing so, as de Vries let the Portuguese driver do all the hard work.

Five laps later, Sergio Sette Camara (Dragon/Penske Autosport) and Mitch Evans (Jaguar Racing) clashed, with the Brazilian sent off into the gravel and out of the race and the New Zealander forced to retire in the pits. A fourth spell under the safety car followed, while Mercedes informed de Vries he had energy in-hand to push leader da Costa with 13 minutes plus one lap to run.

The pack was once again let loose with less than 10 minutes to run, and da Costa controlled things at the restart, though de Vries had a couple of percent of usable energy in-hand over those around him — the leader still needing to use his second dose of Attack Mode. Da Costa intelligently combatted this with Fanboost used to create the gap needed to jump through the activation zone and stay ahead of de Vries.

Behind, Nato slid into the gravel in the battle for sixth, allowing the Envision Virgin Racing pair of Frijns and Cassidy past. They’d eventually move into fifth and sixth respectively, with a Lynn error spilling the Mahindra racer down to seventh.

Wehrlein, meanwhile, also found the gravel and fell out of a points-paying position and eventually into pitting and Mortara and Andre Lotterer (TAG Heuer Porsche) clashed, leaving both out of the running.

By the time the safety car peeled off the circuit after its latest outing, the race had become a straight two-lap sprint. However, with the safety car so busy, and the race running to an extra lap than many had accounted for, only a handful of drivers looked like they’d enough energy to make the finish.

The finish… but not the finish. This is why energy management is perhaps THE most important aspect of Formula E#DHLValenciaEPrix @DHL_Motorsports pic.twitter.com/nDeYQvK08H

De Vries had worked it best, taking the race win from Mueller and Vandoorne, sending the Dutchman to the top of the standings from teammate Vandoorne and Mercedes-EQ to the summit of the teams’ pile.
